Halfway Between 40 and 521

When you ask "What number is halfway between 40 and 521?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=40 and Y=521.

Halfway Between Line

To find the number halfway between 40 and 521, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 521 into our formula, we get:

(40 + 521)/2 = 280.5

Thus, the number halfway between 40 and 521 is 280.5.

To check that our answer is correct, we subtract 40 from 280.5 and subtract 280.5 from 521 and compare the two numbers:

280.5 - 40 = 240.5
521 - 280.5 = 240.5

As you can see, the halfway number is 240.5 higher than 40 and 240.5 lower than 521. Therefore, our halfway between answer of 280.5 above is correct.
